REED ADAMS, OF LAPEER, MICHIGAN.

PRINTING DEVICE.

Application filed August 31,1906. Serial No. 332,740.

Specification of Letters Patent.

Patented Oct. 15, 1907.

To all whom it may concern:

Be it known that I, REED ADAMS, a citizen of the United States, residingat Lapeer, county of Lapcer,

' State of Michigan, have invented a certain new and useful Improvementin Printing Devices, and declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it pertains to make and use the same, rcfcrence being hadto the accompanying drawings, which form a part of this specification.

This invention relates to printing; it has for its objcc't an improveddevice which admits of the quick change of a portion of the typecontained in a chase, without unlocking the form or dis-arranging anyparts except the parts that are changed. This enables a printer to printrapidly, circular letters or similar printed matter. and to change thename of the person to whom the letter is addressed and the place ofaddress and similar parts of the letter which may be required where asingle copy only is sent to one recipient, and where only one or a fewpersons are addressed at a particular place.

In the drawings :Figurc 1, shows a form contained in a chase with theparts embodying the invention contained therein. Fig. 2, is an elevationshowing a single one of the interchangeable parts; the figure being asection through the chase along a line drawn through its center portionfrom top to bottom. Fig. 3, shows a section through a slot in which thelinotype is held without spring quads.

l, indicates the chase; 2, a form locked up therein, and as a part ofthe form, there are locked with the other type and parts connectedtherewith, a number of leads 3, l, 5, and 8 spaced by quads 6 and 7,leaving slots between the quads G and 7, and the contiguous leads ateach side of the quads 6 and 7. Each of these slots is partly filled bya spring quad 9; this spring quad is of peculiar construction consistingof a body part 10, slightly shorter or lower than an ordinary quad andhaving secured to the face thereof a leaf spring ll which bends over theend and toward the back of the quad furnishing an inclined springsurface 12 that reaches from near to the top of the slot to near thebotthcreof. This spring, it is evident, extends lengthwise of the frameor chase as a whole, so that the shaping up of the type in theindividual lines, as respects its position near to, or far from, oneside or the other, it is unaffected by the presence or absence of theremovable linotype bar 13. It will be noted from an inspection of Fig. 2that the further toward the tip of the spring and away from the quada-block or linotype bar 13 engages against the spring, the greater isits distance from the body of the quad itself because of the constantoutward trend or extent of the sprin A linotype bar 13 slightly smallerthan the space between the quad G and the spring quad 9 and providedwith suitable printing matter on the face engages in the slot betweenthe quad 6 and the spring 12 of the spring quad l0; this linotype can beinserted or removedreadily and easily by catching it at the end a androcking the end b on the inclined surface of the spring 12. An expertoperator is able to insert two or three such linotypes in suitable slotsin a few seconds so that when the impressions are taken on an ordinaryGordon press, an operator can remove one set of linotypes and insertanother set of linotypes practically without stopping the press, or bystopping it for a very brief interval, and is thus enabled to printcircular letters with the proper individual address at the head thereofvery much more rapidly than the same circulars could be printed andsubsequently addressed by a typewriter, and moreover when this device isused, the printing of the address and of the body of the circular is inthe same ink and in identically the same type, properly spaced and inproper alinement.

A modified form may be used without spring quads in which case thelinotype bar 23 engages between quads 16 and 17 and is made slightlythinner and shorter than the slot into which it can be inserted and fromwhich it can be removed with celeiity after a little experience. Thefirst form described is preferable.

What I claim is 1- 1. A quad provided with a spring secured to the frontthereof, inclined from the front to the rear with a divergence from thebody of said quad greater at the rear than at the front, whereby alinotypc body may engage thereugainst and be rocked thereon,substantially as described.

2. A spring quad, having in combination a quad body, a spring secured tothe face thereof and extending from the face toward the back thereof butinclined with respect to said quad body, and with a greater divergencetherefrom at the rear than at the front, substantially as described.

3. In combination with a printing form, composed of type blocks andquads arranged to form a slot, a spring quad located at one end of saidslot and having the spring of said quad extending into said slot on anincline and diverging from said quad body toward the back of said slot,whereby a linotypc inserted in said slot may bear against the inclinedface of said spring and be rocked thereon, substantially as described. I

-.'L In combination, a printing form provided with a slot for thereception of a linotype, a yielding quad pr0- vided with an inclinedyielding face projecting into said slot, and a linotype adapted to beinserted in said slot or withdrawn therefrom by pressing the saidlinotype endwise and rocking it on said spring surface, substantially asdescribed.

In testimony whereof, I sign this specification in the presence of twowitnesses.
